Tobias Ellwood: My hon. and learned Friend makes a powerful point and I acknowledge his expertise and interest in the area. The logistics of getting humanitarian aid across the country are severely limited, because aid has to go through the main port of Aden in the south. It is therefore critical that the port of Hudaydah on the Red sea coast is opened up as soon as possible. That cannot happen first of all because it is in Houthi hands, and secondly because the cranes have been damaged, which is perhaps a smaller issue. It is priority for the UN envoy, Ismail Ahmed, who will be discussing opening that port as soon as possible to allow aid to get in swiftly to the rest of the country.
